Focus Industry ENERGY REBATES | 01/09 | Heat Recovery A major byproduct of the air compression process is heat. The new system is designed to recover the heat of compression to supplement building heat in the winter and further reduce costs. Verified Results The projected energy consumption for a system equivalent to Boeing’s original nitrogen generator, but with higher capacity, was an estimated 2,150,000 kWh per year with a peak each month of 225 kW. Projected annual electrical costs would have been $76,400 including peak demand charges. The electrical operating cost of the new system, without the demand charges, has been verified at only $12,730 per year for a savings of 84%. Further liquid nitrogen savings are estimated at $30,000 per year. This operator’s screen allows Boeing to monitor the efficiency of the Manitoba Hydro designed control system. Reliability and Efficiency “Our new Air Liquide nitrogen system is much more reliable and cost effective than either the gas generation or liquid vaporization we previously used,” says Gerry Glor, Boeing Winnipeg’s Autoclave Subject Matter Expert. “And our partnership with our local utility really helped out.” This project is another example of how an innovative design team can come up with a superb solution to a production problem, in an energy efficient way. Boeing and Air Liquide’s design team are commended for their innovative design and the resulting low per-unit nitrogen cost. A great example of being Power Smart®! ® Manitoba Hydro is a licensee of the Trademark and Official Mark For more information, please contact Ron Marshall, CET, CIM, Certified Energy Manager, Industrial Systems Officer, Business Engineering Services, Manitoba Hydro, tel: 204-474-3658, email: rcmarshall@hydro.mb.ca www.airbestpractices.com 15 http://www.airbestpractices.com
